Mobile Battery Power Bank Circuit Diagram

The first module is a lithium ion battery charger and the second is a dc dc boost converter module.

Mobile battery power bank circuit diagram.

Circuit diagram of the power bank is shown in fig. This article will help you to design a portable cost effective power bank with variable dc output hence you can change the output voltage range depends on your phone battery specification. To backup energy when need a portable mobile phone. Turn the slide switch on.

When we need to take the mobile phone to the outdoors that no electrical outlet. When electricity outlet to plug in to recharge a battery. And if thety often use mobile phones. The mobile phones battery starts to get charge from the power bank.

This power bank can be used for charging smartphones. Power bank modules connection diagram it contains three stages first one is tp4056 li. Circuit and working for power bank. The power banks are additional power source and it ensures the power backups when we travel or in emergency situations.

Connect the usb to micro b cable to the output of boost converter. The power is stored in power ban by charging and it can be used when you need in any power bank a battery or combination of some small special batteries cells used to produce the power source to provide for mobile or other electronic gadgets battery charging. This power bank circuit uses two integrated modules and a lithium ion battery. It uses a low dropout voltage high efficiency lm1086.
